    * io/list_read.c (finish_list_read): Read one character to check
    for the end of the file.  If it is the end, then issue the file
    end error message.  If not, use eat_line to reach the end
    without giving error.  The next attempt to read will then
    issue the error as described above.
    * io/read.c (read_decimal): Quickly skip spaces to avoid calls
    to next_char.
    * io/unit.c (is_trim_ok): New helper function to check various
    conditions to see if its OK to trim the internal unit string.
    (get_internal_unit): Use LEN_TRIM to shorten selected internal
    unit strings for optimizing READ. Enable this optimization for
    formatted READ.
